Sandwich pot steam generator _ _ supporting steam generator coal-fired steam generator

Using the most sophisticated three return all wet back structure, safe and reliable; using corrugated furnace and threaded pipe, increasing the heat transfer effect, improving the thermal efficiency; unique large combustion chamber design, increasing the radiation heating furnace area, narrow the volume of the boiler, reducing Nox emissions; multistage seal around the smoke chamber, to ensure that no dew smoke; adopts PLC control, multi-chain protection. Large steam space, good steam quality; adopt effective thermal insulation materials, boiler outer surface temperature is low, the heat loss is negligible; in strict accordance with Chinese national norms and standards, all of boiler pressure parts are made of high quality steel; every boilers undergo a rigorous inspection and testing, including pressure testing and X-ray inspection. Specifications of boiler capacity boilers to produce steam or to heat water and levels. Steam boiler specification unit time to generate steam and steam parameter indicates the number of hot water boiler specification unit time to the heat and hot water for the parameter represents. Number of steam boilers produce steam per hour called evaporation of the boiler, also called capacity or output of the boiler, usually the symbol "D", said unit t / h (t / h). Evaporation of the boiler on the nameplate typically rated evaporation, ie steam boiler at a predetermined parameters and water temperature, continuous operation must guarantee maximum evaporation. Hot water boiler capacity per unit time is water in the boiler's heat absorption unit as MW (megawatts), which referred to the rated thermal power rating or rated for heat. How much media heat boiler and steam production is directly related to the number of boiler heating surface. Boiler heating surface is separated from the flue gas and water vapor, and the heat from the former passed to the latter's metal wall, usually cylindrical wall tube or steam parameters of steam boilers in the boiler main steam valve at the outlet of the steam pressure (gauge pressure ) and temperature represent. Medium parameters hot water boiler with rated water pressure (gauge pressure) and rated outlet / inlet temperature represents. Pressure and temperature, respectively, the symbol "p", "t" represents. Scope: family, small hotels, small enterprises, small size, easy placement, easy to move. 1, the product volume is less than 30L, national exemption in the boiler, ie without going through the boiler use permits. Meanwhile, the product has a large steam space, good steam quality. 2, automatic intelligent control technology, no staff on duty. Work flexible and can be set to manual or automatic boiler may need to be set to run automatically according to the time period, a day to set up a number of different working hours, the boiler automatically start sharing each heating group heating group cycloconverter cut, so the contact TIME, the same frequency, increase equipment life. The controller for pressure control, calculation, tracking changes in the load to the pumps, electric heating tube automatically stop, and can also be manually controlled. 3, with a number of complete protection, leakage protection, water protection, ground fault protection, steam overpressure protection, overcurrent protection, power protection, the boiler automatic protection, safe home. 4, the boiler body with boiler plate, vertical furnace, girth welds are welding, and X-ray testing, small boiler furnace, mechanical and electrical integration, easy installation and patching; large boiler furnace and electric control split designed to eliminate the influence of electrical control temperature furnace, ensure the stable operation of electrical controls. 5, compact structure, scientific and rational design and advanced manufacturing process, so that a small boiler space, easy to transport and saves space. No noise, no pollution, high thermal efficiency, boiler insulation material of high quality and efficient insulation, low heat loss and energy saving. 1) gas boiler and burner control system jointly completed a number of programmable devices reliable control and protection functions; 2) boiler temperature display, temperature control, over-temperature alarm and other security systems set up independently. Gas boiler water temperature control and overtemperature protection are three different sensor completion signal transmitted by the complete 3) boiler temperature control and protection of three different control units: Boiler Control System provides multiple temperature protection: A, temperature setting knob to control the temperature. B, boilers boiler water temperature regulator to limit the protection (water temperature reaches the set value of the automatic shutdown). C, boiler controller operating unit electronic temperature limit protection. D, boiler controller Boiler overtemperature protection (water temperature reached 110 degrees automatic shutdown hand manual reset); 4) burner flame failure protection, burner fault turn off automatic fuel shut off valve and alarm; 5) pressure protection: air pressure is too low, the burner does not start, ensure matching with the combustion pressure and operational safety; 7) boiler overpressure protection: by gas boilers at the outlet of the pressure limiter achieve shutdown boiler overpressure protection and alarm signal output ; 8) Gas pressure protection: when the gas pressure is less than the minimum gas pressure switch setpoint and above the maximum gas pressure switch set value, the burner can not start, can be another shock to the normally closed communicating alarm;
